Double-hopper-door device capable of adjusting flow

Abstract

The invention relates to a double-hopper-door device capable of adjusting flow. The double-hopper-door device capable of adjusting the flow comprises a hopper. A base is installed on one side of the hopper. A support is fixedly arranged on the base. An electric pushing rod is installed on the support through a fastener piece. The two sides of the lower portion of the hopper are symmetrically provided with a first hopper door and a second hopper door respectively through a first connecting device and a second connecting device. The end face of the first hopper door and the end face of the second hopper door form a sector structure. A lifting lug is arranged at the bottom of the first hopper door. The lifting lug is connected with the end portion of the electric pushing rod through a third bolt. A first gear is coaxially installed on the first hopper door located at one end of the hopper. A second gear meshed with the first gear is coaxially installed on the second hopper door. According to the double-hopper-door device, blockage of materials is not easily caused, the materials enter a hopper door range through the hopper, the flow direction of the materials is not changed, the materials can successfully pass and can pass the electric pushing rod, and the required flow size is controlled at will within an adjustable range. The double-hopper-door device capable of adjusting the flow is reliable in work and low in cost.

Description

technical field [0001] The invention relates to the technical field of bucket door devices of construction machinery, in particular to a double bucket door device with adjustable flow rate suitable for the discharge port of a hopper of a ship unloader. Background technique [0002] With the development of the economy, more and more port equipment is used, among which ship unloaders occupy one of the main parts. The hopper door device is assembled on the lower hopper mouth of the unloading hopper of the ship unloader, which can control the flow and reduce the impact force of the material when the material enters the material guide trough through the hopper. In the prior art, one side of the lower mouth of the funnel is usually used to open the door and assemble the funnel door device. This method has a simple structure and is easy to install. The electric push rod can be used to push the opening of the bucket door to adjust the flow. However, in actual use, it is easy to bl...
